We are very sorry to hear that. With the explosive growth of the app and the extreme variation of schedules, we tried to account for all possible issues that may arise. However, we acknowledge that we aren't perfect, but are always trying to improve the app.
First, please make sure that your app is up to date. We may have already fixed your particular issue. You can check for updates at the following links:
If your app is up to date, please submit a support ticket above with all the information you can. Is it crashing when you do something specific (like hit a certain button)? Does it always crash at a certain time during the schedule refresh? Does the app completely shut down or does it stay open and display an error message? If so, what was the error message (exactly if you can, or a screenshot would be best)?
We can't fix what we don't know about, so please let us know and we'll get it working for you.
